Oblivion

Oblivion, the fourth game in the Elder Scrolls series, is set within the province of Cyrodiil, the heartland and Imperial capital of Tamriel. Emperor Uriel Septim VII is assassinated in flight from his own palace, but just before he dies he passes to you - the foreordained of his dreams - the mystic Amulet of Kings. The adventure begins with the quest to find Uriel's lost and illegitimate son, the only heir to the throne. In a world where the forces of darkness seek their ultimate dominion over the ranks of man and mer alike, you alone stand between the future of Tamriel and the gates of Oblivion.

As of June 16, 2009, The Elder Scrolls IV: Oblivion Game of the Year Edition and Game of the Year Editions Deluxe are available to buy from Steam

The Plot
Emperor Uriel Septim VII : I was born 87 years ago. For 65 years I've ruled as Tamriel's emperor, but for all these years, I've never been the ruler of my own dreams. I have seen the gates of Oblivion, beyond which no waking eye may see. Behold, in darkness, a doom sweeps the land. This is the 27th of Last Seed, the year of Akatosh, 433. These are the closing days of the third era, and the final hours of my life.
